Dum-dum face

One of the most powerful insults in history, it is said Stalin said “dum-dum face” to Adolph Hitler, and he committed suicide because of it, apparently Samuel Morse wanted to make Morse code “dum-dum face” but it was too powerful, if he tried he knew he would explode

Stalin: Hey hitler, ur a dum-dum face
Hitler: *proceeds to shoot himself in the face*
